"The offer was made and we've accepted," Sanders said. "North Korea made several promises. We hope they would stick to the promises. If so, the meeting will go on as planned."

Sanders noted the Trump administration's actions on North Korea over the past 13 months, which include tightening sanctions and sailing an armada of military ships toward the Korean peninsula, are starting to have an impact.

"We know the maximum pressure campaign is working," Sanders said. "We know they responded to that. They have pushed this message through the South Koreans to us."

A date and location for the meeting have yet to be announced, although it is expected to take place in the next few months.

An upcoming meeting between President Donald Trump and North Korean leader Kim Jong Un will go on, assuming the rogue nation adheres to promises it has made, White House press secretary Sarah Sanders said Monday.
